They seem okay but I didn't look at them too close. I'm thinking the metal just absorbed and held a lot of heat and that's why the trailer plug partially melted. All the wiring in the area seems to be okay. I modified the tailpipe a little, dropped the outlet lower and cut a little different angle in the end to try and stop it from happening more.
Got the 454 on the engine stand today. It's a big, heavy beast. I added some support under the balancer because I feel like the 1000# Harbor Freight engine stand is about to collapse. Haha.

Jegs has a $25 engine cradle with casters I might get to use instead. It's just a b*tch to move the motor around on the stand.
